ROBERT STERLING NI SPRING PROTECTQTR,

Application fl ed Getobc 30. 1924.

To all whom m z coi'mern Be it known 1h t l. norin" heirs. a citizen of 'lhe l niied .-t--."s. r

at Duncan. n the unty t wte niens and i tate ot Oklahoma l=ve invented. ertain new and use ul l ..'ove2 :euts in t prinjlj Protectors or 3.1! Iary F pii: In. of' whi h e following! is a speci -ation. reference inn had to the acconiiwnyiuadr wings. lhis invention relates to de i es used on ord cars tor the inn-pose o pr venting the breaking of the trout spring and the obiect ot the invention is to pro ide sprint); protector or a utiliary s 'irinfr which. in addition to s rengthening the orie inal spring;- on the forward lYlP of a Ford c r. w ll pre vent the ody ot the car from s ine in r from one side to the other.

Further oh ect is to provid a construction of this kind which will not be detrimental to the trout clamp on a ord car and which will not have anv tendency to strip the threads on the clamp bolt.

.3 still fu ther obiect s to provide a deice of this character wh h. hen used on Fo d cars bavine shock absorbers. will not pe mit the tender to scrape or come in contact with the casing.

Other ob ects wil appear in the course oi the following? description.

My invention is illustrated in the accompanying: drawine. wherein:

Figure l is a tront elevation of a portion ot a radiator. spring and supporting member of a Ford car. showing: my invention applied thereto. the supporting member being partly in section:

Figure 2 is a perspective view of my im proved sprine protector:

Figure 3 is a vertical section through the middle of the spring and the supporting: member showing my protector in place:

My improved protector or auxiliary spring comprises a strip of spring metal having normally a thickness of about one-quarter of an inch. which is bent to form an upwardly bowed middle portion 10 and at the ends the strip is bent upward and then inward or toward the middle to provide spring leaves ll. these spring leaves being! spaced from the body of the spring. as at 12. The body ot the spring: at the center is formed with an aperture l for the passage of the center bolt 14.

This device is disposed upon the spring 15 in the manner illustrated in Figure l, and

between this spring if and the cross beam I? upon which the body of the automobile is supported and which I isposed inst be ow the terde" "i" the aittonio- This beam 16 nneihaped so as to embrace the sprine; t the rwe ll bowed portion in oi 91v de ice lie int-on the pwardly bowed middle po tion o the string. with he portions it eiendinar inw rd and. downward at n sli ht anojlc M'NNUY H'lHtilY the same as the n rle ot the upper wall of the beam 16 so that this beam 16 res s upon these open spr nq biQ'htS 11.

lVith this construction. any downward n'iover'ient ot the body relative to the springs is resisted by the parts .1 which are resiliently held azyainst closinrr downward against the bo y ot the sprinrr. This device. as Will be seen. not onl s rengthens the original sprint? and eliminates a good deal of the tennency to break. but prevents the body of the car from swincring from one side to the other because the beam 16 rests upon these upw rdly inclined ortions l o my spring. T e spring i entirely concealed trom View within the cha nel-shaped beam and is equal to an add tional leat given to the spring. thus pe torniin two functions. As cons ucted. when lace there is no tendency on the part of this spring" to strip the threads on the clamp bolt nor are the tenders allowed to scrape or come in contact with the asing.

It will he und rstood that this device is particular y adapted for Ford automobiles. which are rela ively weak at this point. and in which the body has a tendency to rock upon the middle oi the spring transversely of the line of draft. My device increases the effective point of contact of the beam with the spring 15. thus reducing or preventing this lateral swinaine tendency.

on rough roads or when the car strikes an obstruction which raises one of the trout wheels and tends to cause the body of the car to rock from side to side. this attachment tends to stabilize the car and prevent the encessive rocking due to rough roads or iars. and thus keeps the spring; trom moving side wise on the clamp bolt and strip the threads and shear the same. M'any Ford cars do not have a double clamp bolt but only a single bolt and where this is used this attachment tends to prevent any rocking ot' the car which is disastrous on the front springs. lVhere shock absorbers are used in connecloo tion with a car such as a Ford, there is a greater tendency to sidevvise motion due to the elasticity gained by the use of the shock absorbers. This causes the car to rock to such an extent that the tenders often scrape on the wheels. My device greatly eliminates this tendency to rock and thus prevents the tenders from coming in contact with the trout. tires.

I claim The combination with an automobile having an upwardly bowed trout spring and a supporting beam channel-shaped in cross section fitting over the middle of said spring and having upwardly divergent end portions, of a spring protector and auxiliary spring disposed Within the beam and resting upon the upwardly bowed spring and comprising a relatively thick strip of resilient metal having a Width approximately equal to that of the spring, the middle portion of said strip being upwardly bowed so as to fit upon the spring, the extremities of the strip being upwardly bent and then centrally, medially and downwardly bent in approximately a straight line normally disposed at a less angle to the horizontal than the angle of the upwardly divergent end portions of the supporting beam, but the ends of said portions being spaced from the body of the spring.

In testimony whereof I hereunto ailix my signature.
